To all whom itmagi aonoem:

Be ioknown that I, LEANNA V. DANIELS, a citizen ofthe United-States, residing at 'Elkton,in the county of Brooki'ngs, State of South Dakota, have invented certain new and useful Improvements in Flour-Sifters; and I do hereby declare the following to be a. full, ole'a r, enieXect description of the in- Von-hon, such as will. enable others slniiedm the art to which it apperteins to make and use the same.- I I This invent-ion relaiesto Sifters and more especially to an improved sifter for use in sifting flour emithe ob ect of the invent on 18 to provide a srfter having a body with :1.

series of superimposed senii-spherioai sieves and eplumlity of simultaneously actuated agitators movable therein so that a. complete and thorough sifting or the-flour may be ohpassege of Another object of the invention is so 'gpromole agitators ror each or the moves, said.

the section of meiei the hoiiy pivotal movemenffi' therein. The centralmost of the horizontal portions is extended through the bar 2 in a similar manner but is extended 011t= Wardly at right angles for the attachment of a loosely mounted operating handle 23 which is "adapted to be vertically recipro cated in the actuation of my improved agi-' tator.

In the operation of the device, the ma terial to be sifted is placed within the body and upon the upper sieve and owing to the condition thereof, certainof the material will fall through the' remainingsieves but in order to thoroughly agitate the material to break up the lumps and to force the latter as well as the remaining material through the sieves, the handle is reciprocated vertically. In this action said handle describes an arc of a circle with the ends of the wires forming the agitators as pivots and the semi-circular portions 16'are thus reciprocatecl in contact with the inner surfaces of the sieves to thoroughly sift the material therethrough. By the provision of a series of superimposed sieves having simultaneously actuated agitators, the same can be operated by asingle reciprocating handle and the sifting operation thus accomplished in one operation of the passage of the material through the sitter. By the provision of the openings 15,. the unsifted particles may be readily emptied from each sieve and furthermore the particular man-, nor. of supporting the sieves through the medium of the agitating wires renders the construction extremely simple, durable in use and economical in the manufacture. As will also be noted from the drawings, the uppermost sieves extend into the sieves therebeneath for a suflicient distance to permit a greater number of the said sieves to be placed within the body and also to'form a discharge spout in efi'ect, for each sieve in connection with the openings in the body to permit the proper emptying of the unsifted i particles therefrom,- and also to restrict the space between the respective sieves so that the material willbemore quickly and thoroughly sifted.

I clai'mz In a flour sifter, a cylindrical body havingopen'upper and lower ends, semi-spherical sieves arranged one abovethe other Wlth in the body, agitating wires having their ends mounted in diametrically opposite sides of the body to support the sieves and having semi-circular portions extending in contact with the sleves, common ends of the Wires being bent at right angles and in parallel relation, a connecting member for the ends of said last mentioned portions and a handle for reciprocating the connecting member and simultaneously oscillating the agi tators.

In testimony whereof, I aflix my signature in presence of two Witnesses.
